Alternate Positive & Negative Numbers | Easy Coding Problem Solution (Step-by-Step)
In this video, we solve the classic coding problem of rearranging an array to alternate between positive and negative numbers without changing the relative order. We'll walk through the solution step-by-step and discuss the logic behind maintaining the sequence efficiently. Whether you're prepping for coding interviews or brushing up on problem-solving, this tutorial will help you understand the approach with ease!
Example Problem:
Array: [9, 4, -2, -1, 5, 0, -5, -3, 2]
Output: 9, -2, 4, -1, 5, -5, 0, -3, 2
Key Concepts Covered:
Efficient array manipulation
Maintaining order of elements
Time complexity: O(n)
